A Physicist Tries to Avoid the Fact of Design in Our Universe…

Physicist Alexander Vilenkin of Tufts University argues, against apparent fine-tuning, that our universe’s cosmological constant should have a special value like zero, but doesn’t

In his discussion with Robert Lawrence Kuhn at Closer to Truth, Tufts physicist and cosmologist Alexander Vilenkin addresses the question, “Is the Universe Fine-Tuned for Life and Mind?”: If the deep laws of the universe had been ever so slightly different human beings wouldn’t, and couldn’t, exist. All explanations of this exquisite fine-tuning, obvious and not-so-obvious, have problems or complexities. Natural or supernatural, that is the question. Vilenkin — who is also a professor of evolutionary science — concedes the main point: Alexander Vilenkin: [0:40] Well yeah that’s right. It appears that the Universe is fine-tuned in the sense that there are about 30 constants of nature which take some specific value: if you look at these numbers, they look Read More ›

Maybe There Are Just Very Few Aliens Out There…

The Rare Earth hypothesis offers science-based reasons that life in the universe is rare

Recently, science and science fiction writer Matt Williams has been writing a series at Universe Today on why extraterrestrial intelligences never make contact with us. Last week, we looked at the hypothesis that, to avoid the heat destruction of their advanced technology, the aliens have put themselves into a digital slumber until the universe cools down. This week, let’s look at a quite different approach, which Williams outlines in “Beyond “Fermi’s Paradox” IV: What is the Rare Earth Hypothesis?” (July 29, 2020): That is “the possibility that life-bearing planets like Earth are just very rare.” We don’t see aliens because they are very uncommon: This is what is popularly known as the “Rare Earth Hypothesis,” which argues that the emergence Read More ›
